See i am very big fan of watching ANIME & DONGHUA (Chinese anime), so there was some episodes from an anime which didn't have any subtitles to it, i searched all over and didn't got it, so then i started searching for any software tool that can add subtitles to the video, i searched got some, but it was asking to buy credits and all... well it is not wrong because running an ai service consume huge tokens so it is expensive... but i do not want to spend $3-$4 for just 1-2 videos that does not have subs.. so there i took the decision to build my own and use it... i thought of the architecture that does not rthat needs to used for making it and use it in free way without paying a penny,
